TCP/IP Configuration
In order to enable data communication between amplifier and a PLC or a web browser,
the Ethernet settings must be known. In a PROFINET-network the system designer
configures the address for each device and has therefore an overview over the
distribution of the addresses in the network. The IP-address is assigned to each device
via the PLC. The device must have an IP-address of 0.0.0.0 after power up to enable the
assignment of the final IP-address. This is the case after each EMGZ490A restart.
Static IP-address:
A static IP-address is required to enable the PLC accessing a web interface. The IP-
address of 0.0.0.0 cannot be used for this purpose, as this address is treated in a
special way according to TCP / IP–specification. Devices with this IP will not response, if
an inquiry over the web browser is started.
5.3
System Start-up
At system start-up, the communication between IO-controller (PLC) and IO-devices is
established and necessary parameters are set. The parameterisation is only performed,
if the system is accordingly configured. Otherwise, the locally stored configuration in
EMGZ490A is used. Parameters can always be changed via the web interface.
5.4
Data Exchange
The EMGZ490A uses the typical PROFINET communication methods. For rapid
transmission of the measured data cyclic data traffic is used. For the parameterisation
acyclic data traffic is used. For the transmission of limit violations also the cyclic data
traffic is used.
